Super-large-diameter deep shaft simple shield device and shielding method

Abstract

The invention provides a super-large-diameter deep shaft simple shield device and a shielding method. The simple shield device comprises a soil cutter, a pipe piece supporting base, an excavating cutter head, a steel plate ring shaft wall, a concrete pipe piece and matched construction devices. A concrete pump truck, a crane, a pipe piece pressing machine, a loader, a slag stone vehicle, a welding machine and other matched devices are arranged above a shaft. An excavator is matched with the bottom of a shaft, and a slag stone conveying device is installed on the position from the bottom to the top of the shaft. The method is simple, the property is reliable, the devices are mutually matched, the mechanical construction requirements of the super-large-diameter deep shaft are met, work efficacy and construction speed of the super-large-diameter deep shaft are greatly improved, the supporting effect of shaft construction is greatly improved, and the collapse risk is reduced.

Description

Technical field [0001] The invention relates to a simple shield device and a shield method for a super large diameter deep shaft. Background technique [0002] In recent years, with the gradual expansion of the scale of various transportation infrastructures in my country, higher requirements have been put forward for the construction of large-diameter deep shafts. The characteristics of my country's shaft shaft: deep shaft, large cross-section, complex geological conditions, resulting in complex construction technology and long construction period. In the past, my country’s shaft shafts mainly used long-section single-line operation methods, which increased the auxiliary operation time. Moreover, the cast concrete shaft wall used movable metal formwork, which was low in mechanization, which severely restricted the overall construction progress. Due to the backward support measures, the collapse could not be solved. problem. Summary of the invention [0003] The invention solves ...

The characteristics of shaft shafts in my country: deep shafts, large cross-sections, and complex geological conditions lead to complex construction techniques and long construction periods

In the past, my country's shaft shafts mainly used long-section single-row operations, which increased the auxiliary operation time, and the pouring concrete shaft walls used movable metal formwork, which has a low degree of mechanization, which seriously restricts the overall progress of construction. Due to backward support measures, it is impossible to solve the problem of landslides. question
